Description:
------------
Note below that the For loop's left bracket does not immediately follow the for loop
conditional's right closing bracket. The interpreter does not throw an error and permits this
code to execute. Result: For loop does nothing - whether it tries to execute, gets confused, or
simply ignores the code - I don't know - the actual result is the program runs and the For loop
fails.
Fix: Once the interpreter detects a for loop the syntax checker should demand an opening bracket to
immediately follow the closing paren on the for loop's conditional.
Test script:
---------------
for ($ib = 0; $ib < $ncountp; $ib = $ib + 14)
$ib1 = $ib + 1; $ib2 = $ib + 2; $ib3 = $ib + 3;
$ib4 = $ib + 4; $ib5 = $ib + 5; $ib6 = $ib + 6;
$ib7 = $ib + 7; $ib8 = $ib + 8; $ib9 = $ib + 9;
$ib10 = $ib + 10; $ib11 = $ib + 11;
{$ib12 = $ib + 12; $ib13 = $ib + 13;
if (isset($ivcarrp[$ib13]))
{if ($ivcarrp[$ib13] == "XX")
{$bypasscnt++;
continue;}
}
}
